MDD025B-N-100-N2G-040PD0
The MDD025B-N-100-N2G-040PD0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, the unit converts commanded phase current into accurate rotary motion so that pick-and-place heads, miniature conveyors, and test fixtures can follow tightly controlled position or velocity profiles. A compact stator design, together with high rotor speed capability, lets machine builders integrate multiple axes inside restricted spaces while maintaining the dynamic response needed in automated production cells.
Mechanical alignment begins with a 40 mm centering diameter, which provides a repeatable pilot fit that keeps the housing concentric to the load flange. The continuous standstill torque of 0.60 Nm indicates how much force the motor can supply during holding or slow-speed tasks without exceeding its thermal limit. During normal operation, the rotor can reach a nominal speed of 10000 rpm, making the device suitable for high-throughput stations that rely on rapid indexing cycles. Vibration control is supported by standard balancing, and electrical power and feedback exit the rear through a connecting cable with a coupling unit that provides a detachable interface when the machine frame blocks direct access to the motor terminals.
The feedback loop is closed by resolver feedback, allowing the drive to calculate rotor angle under high acceleration. Torque is transmitted through a keyway shaft, and the front bearing region is supplied with a shaft seal to help limit contaminant ingress. The motor corresponds to size 025 and length code B, so the overall envelope and mass remain low for robotic wrists or linear stage carriages. Connections are oriented on side B, and the unit is delivered without a blocking brake to reduce inertia during fast start-stop cycles.
